2006 Street Glide Harmon Kardon Radio Problem

The backlight in my 2006 Street Glide quit working. So night tuning is out of the question. Is there a way to fix this or do I have to send it back to Harley Davidson? Thanks

The cd player on my 06 street glide(harmon kardon) skips with minnimal road vibration

1-check condition of CD
2-be sure fairing brackets on bike are not broken
3-be sure riser bolts are not making contact with the bottom of the radio

if all of the above are OK, it's either a defective CD drive or bad SDRAM circuit (40 second buffer memory). The unit will need to be repaired. For repair options, contact Iron Cross Audio.

Installing a Harmon Kardon on a 03 Ultra

The 23 pin main connector is a direct plug in from the 03 bike to the HK unit. The only issue would be if the original 03 was using the accessory connector as well. The accessory connector on the 03 is another 23 pin. It's a 35 pin on the HK. For more info, or to discuss this further, contact Iron Cross Audio (
